This invention relates generally to stokers and particularly to an ash'elevator for use'inconjunotion therewith.

.The'mai'n object of this invention is to provide a means foraccumulating and storing ashes that will utilize most advantageously thespace that maybe available near tlie'boiler or furnace. Inother'w'ords'jl have endeavored to obtain the maximum practical stora'gecapacity when 'occu 'pyin'gthe minimum number of square Qfee t jof floorspace.

The second object is to provide a simpl and eificientform ofdistributingmechanismand storage buckets which will provide themaximurnamount of ash storage without requiring an unof storage can which willnot be'difjcult to empty.

The fourth object of this inventiojnis to socjonstruct the ash handlingsystem that the yarioiijs joints may easily be'renderd dustjtight.

The mechanism thus far described collects ashes from the furnace l andelevates them and discharges them through the tube 34. Any equivalentmechanism for accomplishing this purpose may be employed withoutdeparting from the spirit of this invention.

Turning now to my invention as more clearly set forth in Figs. 2 to 6,it will be seen that the ash distribution and storage unit consists ofan outer casing 56, over the top of which is placed a removable cover 5!and beneath which is formed a floor 58. Disposed under the floor 58 area battery of ash cans 59, which are shown in plan in Fig. 5. Each ashcan 59 is elongated, as shown in Fig. 6, and tapered about one fourthinch per foot. In normal practice the cans are about four and one halffeet tall and six inches square at the top, and about four and one halfinches square at the bottom. All four sides are tapered, but a lessernumber may be tapered without seriously detracting from the utility ofthe device. Around the upper end of each ash can 59 is secured an anglebar rim 66, beneath which is secured a handle 6|. Below the handle BI issecured the elongated hinged handle 62, which is made fast to the crossstraps 63.

The floor 58' is provided with a plurality of round holes 64, one overeach can 59. Resting on the floor 58 is a distributing plate 65 providedwith holes 66, all of which can register with the holes 64 at the sametime when the distributor plate 65 is moved in one direction in order topermit ashes to flow therethrough into the cans 59, whereas all of theholes 64 may be closed when the plate 65 is moved into the positionshown in Fig. 2. The plate 65 is provided with two slots 61, throughwhich extend the bolts 68 which, like the bolts 69 disposed beyond theouter boundaries of the plate 65, extend through the short horizontalshafts 16 and the long horizontal shaft ll. The bolts 68 and 69 passfreely through the upright tubes 12, which are secured to the floorplate 58. The lower ends of the bolts 68 and 69 pass through thehorizontal bars 73.

Partition walls 74 extend between the floor and 45 the back of thecasing 56, while the transverse wall 75 extends between the partitions14. The

walls 14 are provided with slots 16 to permit the free vertical movementof the shafts and H.

Mounted on the shafts 10 and H are the rollers I1 and i8. Beneath therollers 11 and 18 are disposed the plates 79, having the inclined camsurfaces 89 formed thereon, upon which the rollers I1 and 18 can rest,as shown in Fig. 3, allowing the cans 59 to move to a lowered position,that is,

one in which they can be withdrawn from the casing 56 by opening thedoor 8i. It is desirable to provide a rubber gasket 82 on the under sideof the floor 58, against which the rim 60 of the ash cans 59 can presswhen the earns 59 are in a raised position, as shown in Fig. 4. Theplates 19 are secured to the distributor plate 65. One set of plates 79are separated, as shown in Fig. 3, to provide clearance for thedischarge tube 34, while the other plate 19 is provided with a slot 83as shown in Fig. 4, to provide clearance for the worm shaft 46, whichjournals in the bearing 84, which in turn is secured on the floor 58 bymeans of the bolts 85. Also secured on the floor 58 is a standard 86,through which extends the discharge tube 34. The end 35 of the dischargetube 34 extends through the wall 14.

Journaling in the bearing 84 and the standard 86 is a shaft 81, on whichare secured the pinions 4 88 and 89 respectively. The pinions 88 and 89mesh with the racks 90 and 9|, which are secured across the top side ofthe members 19 by means of the bolts 92. Motion is imparted to the shaft81 by means of the crank 93.

The operation of this portion of the device is as follows: Assuming thatthe buckets 55 are carrying ashes l4 upwardly on the inside of the belt52, it follows that when they reach the uppermost turn of the belt thatthey will be dumped and fall through an opening 94 in the tube 34, andare then carried by the discharge worm 34 onto the plate 65. It followsthat the ashes will be deposited upon the plate and will fall throughthe nearest holes 64 and 66 if they are in register. .When anyparticular can 59 is filled, the ashes are pushed onto the next nearestunfilled can. If the attendant does not empty the cans, the only damagewhich can occur is to raise the cover 51 and permit the ashes to spillupon the floor outside of the cabinet. If it is desired to remove thecans 59, it is only necessary to rotate the crank 93 which causes theplate 65 to slide to the position shown in Fig. 2, that is, so that theholes 64 and 66 are out of register, the last portion of the movementcausing the cans 59 to be lowered.

While I have thus illustrated and described my invention, it is not mydesire to be limited to the precise form shown herein, and I intend tocover such forms and modifications of the invention as fall fairlywithin the appended claims.

I claim:

5. An ash handling system having an upright rectangular ash cabinet withmeans for elevating ashes to the top of the cabinet in combination witha plurality of elongated vertical ash cans disposed within said cabinet,means for slidably supporting said cans in rows, said cabinet having anopening in the side thereof, through whch said cans can be removed bysliding same horizontally, means for raising and lowering said ash cansupporting means, a floor disposed over said ash cans having openingstherein communicating with said cans, said floor having sealing meansdisposed along the under side adapted to engage said cans when raised,and an apertured plate constituting a sliding valve disposed upon saidfloor, together with a cam attached to said plate, adapted to lower saidash cans when said plate is moved to close the openings in said floorERNEST C.
